Primes¶
- Inspection Paradox
- In software systems, profilers that sample running threads catch long tasks more often, and latency percentiles over in-flight requests over-represent slow ones.
This sourceExplains that a statistical (timed-interval) sampling profiler catches a function in proportion to its on-CPU time, so the profile reports time-share, not call frequency — length-biased sampling over function runtimes.
